The Immortality Key: The Secret History of the Religion with No Name

Brian C. Muraresku's The Immortality Key: The Secret History of the Religion with No Name, St. Martin's Press, 2020, is a currently debated popular scholarly thesis, cited here as a live position rather than an established finding. Its strength is that it engages seriously with recent archaeochemical residue evidence for psychoactive substances in ancient ritual, rather than resting purely on textual speculation. Its limit is that its central argument, an unbroken psychedelic sacrament tradition running from Eleusis into early Christianity, remains contested by specialists in both classics and biblical studies, and should be read as an argued thesis, not a settled scholarly consensus.
